So, I was thumbing through the Chaositech book when I came across statistics for "attack spheres," chaositech spheres that can be used to attack one's enemies. Unsurprisingly, they sound a lot like Sentinel Spheres from Phantasm, so I was immediately intrigued.
Well, naturally, something like that needs more stats (obviously), so I whipped up a quick D&D 4e stat block. The things are designed to be quick and dangerous. Enjoy!
